Former Projects


  • QuadriX

    • QuadriX is a "research tool" for experimenting with the bended faced group of objects, the Superquadrics. This type of objects are a generalization of the sphere equation, giving common and strange new shapes described by the same simple equation. Helwig Löffelmann made some eye-twisting images, by modeling an extended camera, where the viewing rays are shot along the surface vectors of some hyper-super-ellipsoids.
      Some "screenshots" show the GUI of my program, supporting DXF and POV export of the generated models!

  • Qmanip

    • Qmanip is a full interactive Quadtree-manipulator letting you edit both the raster and the quadtree itself. Sample patterns of different size show the application of the raster as fill pattern. Saving, loading, inverting the pattern or generating a random-one is included. It's been made as a homework for the lecture Computergraphik 3 in 1993.

      This screen-shot shows you the GUI.

      Both programs are written in Turbo Pascal on PC. The whole graphical interface with windows, gadgets, ... was generated by me in plain Pascal. I used for the Qmanip the routines again, which were then already collected in a unit.

      Comments to the programs are also welcome be mail here.

  • Ongoing research

    • These former projects I've done during my studies. Information about ongoing research and current interests you will find on my research page.
